  1. Biology SOL REVIEW Review Questions Set 1

  2. Question 1 • Once ____ was shown to be the genetic material, a race among scientists took place to work out its structure.

  3. A-1 • DNA

  4. Q-2 • Studies of the amounts of each DNA base in different organisms led to the concept of ________________________base-pairing.

  5. A-2 • Complementary

  6. Q 3 • Interpretations of X-ray photographs of DNA were used to describe the shape and dimensions of the DNA molecule. An analysis of this and other available data led to a structural model for the DNA which is described as a _____________ ____________

  7. A 4 • Double Helix

  8. Q 5 • What technologies made possible the observation and description of living things and organisms?

  9. A 5 • Magnifying lenses and the light microscope

  10. Q 6 • The ___________ _____________ states that all living things are made up of cells and that cells come from other cells by the process of reproduction.

  11. A 7 • Cell Theory

  12. Q 8 • Who’s experimentation and hypotheses led to an understanding of the presence of microorganisms and their relationship to diseases?

  13. A 8 • Pastuer & Koch

  14. Q 9 • T or F- “The introduction of the germ theory led to the understanding that many diseases are caused by Microorganisms.”

  15. A 9 • TRUE

  16. Q 1 0 • What has resulted from the acceptance of the germ theory of disease?

  17. A 10 • Changes in health practices - the emphasize sanitation, the safe handling of food and water, aseptic techniques to keep germs out of the body, and the development of vaccinations and other chemicals and processes to destroy microorganisms.

  18. Q 11 • About how much of the mass of a cell is made up of water?

  19. A 11 • About 2/3 (or 66%)

  20. Q 12 • T or F- “Water molecules are both _adhesive__ and _cohesive__ due to the nature of bonding.”

  21. A 12 • True

  22. Q 13 • Water is able to absorb large amounts of _____ .

  23. A 13 • HEAT

  24. Q 14 • What are two kinds of bonding that occur with water?

  25. A 14 • polar covalent and hydrogen bonding

  26. Q 15 • T or F: “Because water is able to absorb large amounts of heat, lakes and oceans stabalize air and land temperatures.”

  27. A 15 • TRUE

  28. Q 16 • Why don't lakes and oceans freeze solid?

  29. A 16 • The solid form of water, ice, floats, preventing lakes and oceans from freezing solid.

  30. Q 17 • The water inside and outside of cells is able to carry ____ into and around cells and ____ away from cells.

  37. A 20 • Basic

  38. Q 21 • T or F: “Most organisms can tolerate fairly large changes in pH because every cells easily adapt to pH changes.”

  39. A 21 • FALSE- (Organisms can tolerate only small changes in pH because every cell has a particular pH at which it functions best).

  40. Q 22 • Organisms can tolerate only small changes in pH because changes in pH cause changes in _______ conformation, resulting in a change in activity.
